Three asteroids will pass the Earth this week on trajectories which NASA classifies as a 'close approach'.

Two of them are up to 30metres wide and the third will be closer to Earth than the moon.

Asteroid VS1 will be the first visitor at 2.03pm GMT on Saturday, November 10.

The 30metre asteroid will be around 861,700 miles away from Earth and 16 minutes later will be followed by VR1 - again 30 metres wide, but this one will be 3.12 million miles from Earth - which NASA still classifies as a close approach.
